Application filed April 6, 1922. Serial No. 550,064.

To all whom it may concern:

Be it known that I, CONRAD H. ZIEG, a citizen of the United States,residing at York, in the county of York and State of Nebraska, haveinvented a new and useful Furnace, of which the following is aspecification.

This invention relates to furnaces and more particularly to furnaces ofthe hot-air type, the primary object of the invention being to provide afurnace wherein the maximum amount of heat will be generated from theminimum amount of fuel.

Another object of the invention is to provide a furnace wherein thesmoke and gases which ordinarily pass upwardly through the chimney willbe directed through the body of the furnace to further heat the furnace.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of'theinvention.

Referring to the drawings:

Figure 1 is a front elevational view of a furnace constructed inaccordance with the present invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a sectional view taken on line 33 of Figure 4.

Figure 4 is a sectional view taken on line H of Figure 1. V

Figure 5 is a sectional view taken on line 5-5 of Figure 2.

Figure 6 is a sectional view taken on line 6-6 of Figure 2.

Figure 7 is a sectional view taken on line 7-7 of Figure 4.

Referring to the drawings in detail, the furnace is indicated generallyby the reference character 5 and is constructed of bricks or other wellknown material employed in furnace construction. The furnace is formedwith a firebox indicated at 6, which extends from the front of thefurnace, terminating at a point at the rear thereof. The firebox 6 isalso formed with side walls 7, which are disposed in spaced relationwith the side walls of-the furnace to provide passageways 8, thepassageways being in communication with the'firebox, as through disposedat the rear thereof. 7

As shown, the side walls 7 of the firebox continue to the upper portionor top of the stove indicated at 10, providing lateral passageways,which passageways are divided by the partitioning walls 11, which havetheir lower ends disposed in spaced relation with the firebox top 12 toinsure the heat and products of combustion circulating through the upperportion of the furnace, and at the same time restricting the passage ofheat to increase the suction or draft through the passageways. I

The central portion of the furnace is di vided by a wall 13, whichextends to a point in spaced relation with the top 10 of the furnace toprovide a passageway 14 which is in communication with the centralpassageway as through the opening 13. At the forward portion of thefurnace is a wall 15 which forms a part ofthe chimney 16, the lower endof the wall 15 terminating in spaced relation with the upper wall 12 ofthe chamber 9,

the firebox. The furnace is provided with the usual grate indicated at17 and ash-pit 18. From the foregoing it will be seen that the heat androducts of combustion are carried twice t rough the furnace, the heatand products of combustion taking a path through the chamber 9 asindicated by the arrows as shown by Figure 4 of the drawings, from whereit passes over and under the partitioning wall 11 and to the centralportion of the furnace, through the opening 13', where the same passesupwardly over the wall 13 and to the chimney 16, through the opening atthe base of the wall 15 as shown by Figure 2 of the drawings.

Having thus described the invention, what is claimed as new is 1. In afurnace construction, a fire-box, said furnace including a centralcompartment and lateral compartments, said lateral compartmentscommunicating with the firebox at one end of the fire-box, said lateralcompartments communicating with the central compartment at the rear ofthe furnace,

relation with the upper Wall of the furnace to provide bafiles, andbaffles in the central compartment to obstruct passage of prodnets ofcombustion therethrough.

2. A furnace construction including a firebox said furnace including acentral passageway and lateral passageways arranged above the fire-box,said lateral passageways being in communication with the fire-box at therear thereof, means for causing prod nets of combustion passing throughthe lateral passageways to take an irregular course therethrough, andbafiles in the central passageway causing the products of combustion totake an irregular course through the central passageway.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
